ABLELink® Single Port Serial Server GW51E-MINI
1. Introduction
Atop GW51E-MINI Single Port Serial Server is a gateway between Ethernet (TCP/IP) and RS-232
communications. It allows almost any serial device to be connected to a new or existing Ethernet network.
The information transmitted by GW51E-MINI is transparent to both host computers (Ethernet) and devices
(RS-232). Data coming from the Ethernet (TCP/IP) is sent to the designated RS-232 port and data being
received from RS-232 port is sent to the Ethernet (TCP/IP) transparently.
In the computer integration manufacturing or industrial automation area, the Atop GW51E-MINI Single
Port Serial Server is used for field devices to direct connect to Ethernet network. Terminal Server (main
control program run in GW51E-MINI) transforms whatever data received from RS-232 to TCP port then
connects devices to the Ethernet network via a single application program or multiple application
programs.
Many control devices provide the ability to communicate with hosts through RS-232, however, RS-232
serial communication has its limitations. For one, it is hard to transfer data through a long distance. With
Atop GW51E-MINI, it is possible to communicate with a remote device in the Intranet environment or even
in the Internet and thus, increases the communication distance dramatically.
Flexible configuration options enable this unit to be setup remotely over Ethernet web browser, or Window
utility.

1.2 Application Connectivity
GW51E-MINI supports two connection modes, i.e. TCP server mode and Virtual Com server mode. Each
link mode is fit to deferent applications.
2. Hardware Installation
Plug in DC 5V 200mA, and the RUN LED will blink if GW51E-MINI functions normally.
Prepare necessary cables, hub, power cord and RS-232 connector.
Connect a serial device to a serial port of GW51E-MINI, make sure the right connection of RS-232.
Use monitor.exe configuration utility in the product CD or diskette to diagnose GW51E-MINI. If it
starts up successfully, you are able to find the IP and MAC addresses of GW51E--MINI. You can
change the network parameters of GW51E-MINI to join your LAN by changing its IP address,
gateway IP address and subnet mask.

At right is a sample Virtual COM Control Panel window. At the left is the list of the COM ports that you
have selected (in the Select Ports window) for use by the Virtual COM Redirector. If you wish to change
ports appeared in this list, use the Select Ports button.
Each COM port has its own settings. When you click on a COM port, the Control Panel display changes
to reflect the settings for that COM port.
Note: When you change settings for a COM port, the changes are effective immediately. There is no
separate confirmation dialog to confirm or cancel your changes.
Configuring Virtual COM Ports
You configure each Serial/IP COM port as follows:
1.
Select a COM port in the list.
2.
For IP Address of Server, enter a numeric IP address for the serial server.
3.
For Port Number, enter the TCP port number that the serial server uses to provide its serial
ports to the network.
4.
For Server Credentials, the default is No Login Required. If your serial server does require a
login by the Virtual COM Redirector, the Virtual COM Redirector needs to provide a username
and/or password every time an application tries to use the serial server.
5.
Click the Configuration Wizard button and then click the Start button that appears in the wizard
window. This important step verifies that the Virtual COM Redirector can communicate with the
serial server using the settings you have provided. If the Log display does not show errors, click
the Use Settings button in the wizard, which makes the recommended settings effective and
returns you to the Control Panel to continue with the following steps.

To start the program, please type in the following command in the command line prompt:
TCPTEST2 IP_Address Port_Number
The command tcptest2 10.0.50.100 4660 brings you to connect to a TCP server of IP address
10.0.50.100 and port number 4660, the received data is displayed on the screen and the data typed in is
sent to the TCP server of the designated port number. You can also send binary data in hex format with a
leading character “\”. For example, “\00” and “\FF” represent ASCII code 0 and 255 respectively.
You can also use modem to connect to the serial server. Command "AT\Od" sends standard AT command
to the modem which in return responds with "OK\0D\0A" message to the host application.
Always use '=' then Enter key to exit the program.
